IMPROVEMENT IN CURTAIN-FIXTURES.

The Schedule'referred to in these Letters Patent and making part of thesame.

To all whom 1t/may concern:

Be it known that I, THOMAS STEWART, of Philadelphia, inthe county ofPhiladelphia and State of Pennsylvania, have invented a new and use-fulImprovement in Window-ShadeFixtures andI do herebydeclare that thefollowing is avfull, clear, and exact description of the constructionand operation of the same, reference being hadto the accompanyingdrawing and to the letters of reference marked thereon.

My invention applies to that styleof window-shades where the roller onwhich the shade is wound can be lowered or raised at pleasure, in orderto properly ventilate a room and keep out the rays ofthe sun.

Toaccomplish this I use three peculiarly-constructed brackets providedwith pulleys, two of which are provided with guides, and carry the cordsfor suspending the roller, said cords being furnished with metalliclinks, the lower parts of which are flattened out and made withopenings, in which the journals of the roller-ends turn.

Figure l is a front viewof' m y invention applied to a window-frame. g iY Figure 2 is an edge view of same, with a portion of one of theuprightsbroken away in order to showan end-view of the fixtures.

Figure 3 is a side and front view of one of the brack-V ets used.

Figure 4 is a side view of one of thc links, showing the end of one ofthe cords attached.

To enable those skilled in the art to. make and use my invention, I willnow proceed to describe its con struction and operation.

Secured inthe proper position to the upper part A of the4 windowframeare two brackets, B and Bl, which extend down, and have placed andrevolving in them two pulleys, P and P.

The said brackets are each made with projections or flanges, fand f', ontheir upper ends for attaching them to the frame 5 vandtheir lower endsare extended out, and provided with a slot, .0, iig. 3, through whichthe suspensionfcords are passed and guided in raising and lowering theroller R.

Passing over each of the pulleys P and l are two cords, C and O1, theAends of which are attached` to links, L and L.

The said links are made with their upper' ends in the form of a tube,through which the endof the cord C or Cl is passed and knotted, in orderto prevent it from drawing out,and the lower ends. flattened out andformed with an opening, N, in which'are placed `the journals of theroller-ends. vThe opening N is made larger at .the top than at thebottom, so as to allow the enlarged ends of the journals of therollerends to pass through and drop down, where they are retained by theweight of `the roller and curtain.

Immediately in front of the\bracket B is placed and secured abracketfB'z, provided with anges similar to brackets B and B1.

In said bracket is placed a pulley, I, over which passes au endlesscord, C?. This cord is then passed down and takes one turn around thegrooved rollerend, and thence goes down and passes over an ordinaryshade-bracket secured to the side of' the windowframe.

The'eords C and C1, which pass over the pulleys P and I" and support theroller R, extend down on the opposite side ofthe windo\vframe, (fromwhere the col-d0Z is attached,) and are united and wound over knobsfastened to the side of' the window-frame.

The operation of a window-'shade arranged on tixtures of thisconstruction is as follows:

The roller It is lowered, by means of theords C and G1, as far down asthe window-sill, if desired; and as the roller is lowered the curtain orshade will be wound around it, owing to the revolving oi' the rollerduring its passage downward, which is caused .by the single turn of thecord C2 over grooved roller-end.

1t, desired, the curtain or shade can be raised and lowered, in theordinary manner, by drawing upon the` cords O and G1, and keeping theroller up close to lthe brackets B andB, care being taken to secure thecords O' and Cl aroundthe knobs on the windowframe. v Having thusdescribed my invention,.

What I claim, and desire to secure byfLetters Patent,

The construction and arrangement of the brackets B and B1, provided withanges f and f openings O,

v and pulleys P and I, in combination with the bracket B2, pulley l,roller It, and cords O, O', andl OZ, so as to operate substantially iuthe manner and for th'e .purpose specified. l

',In'testimony whereof, I have hereunto signed my namein the presenceot' two subscribing witnesses.

THOMAS STEWART. Witnesses ISAAC R. OAKFORD, FRANK S'roU'r.
